A longitudinal evaluation of urinary cortisol in kennelled dogs, Canis familiaris.

Urinary cortisol levels (based on cortisol : creatinine ratios) were evaluated in a randomly selected sample of shelter dogs kennelled over a 31-day period. Urine was collected on days 2, 5, 10, 17, 24 and 31 (with day 1 referring to the day of admittance to the shelter). Cortisol levels peaked on day 17 and steadily declined thereafter, although a high degree of individual variation was found, with cortisol levels peaking sooner in some dogs. Cortisol levels in kennelled dogs were significantly higher on all days except d 31 than the baseline measures taken from 20 dogs in their home environments. There were no differences between cortisol levels in male and female dogs on each day of sampling and there was no significant linear correlation between age and cortisol levels. The results are discussed in relation to stress management and the welfare of kennelled dogs.

An audit of behavioral indicators of poor welfare in kenneled dogs in the United Kingdom.

This survey-based study describes the prevalence and onset of behavioral indicators of poor welfare in dogs kenneled at United Kingdom rescue shelters. It describes key factors contributing to individual variation in behaviors. At 8 rescue shelters, staff trained in the care of nonhuman animals recorded daily whether dogs in their care displayed each of 15 behaviors. The study originally involved 302 dogs; for the first 14 days, it monitored only 148 dogs daily. The study observed dogs for a maximum of 6 weeks from admittance, observing all 15 behaviors at least once during the first 2 weeks (n = 148). The proportion of dogs observed to perform each behavior differed within the sample. The most commonly observed behavior (24.3% of dogs) was excessive barking. The remaining 14 behaviors ranged from listlessness (20.3%) to repetitive tail-chasing (1.3%). Over the 6 weeks, the proportion observed to pace repetitively and wall bounce increased. The proportion who lacked appetite and displayed fear-associated behavior decreased. Breed differences, gender, and age partially explained variability in the onset and prevalence of behavioral indicators of poor welfare in kenneled dogs.
